Abstract
A method for manufacturing a heat transfer surface and the surface so manufactured. The porous surface is produced by flame spraying a metal substrate with a mixture of metallic and nonmetallic powder particles. The surface is then heated, causing the nonmetallic powder particles to oxidize into gases which diffuse from the surface, leaving voids where the nonmetallic powder particles were located. The voids provide nucleate boiling sites for a liquid being heated by the surface.
